Abstract (en)
[origin: EP0330043A2] A method of processing a silver halide color photographic material in which the material is, after color-developed, processed in a bath having bleaching ability and then in a bath having fixing ability, wherein a bleaching agent in the bath having bleaching ability is at least one iron(III) complex of an aminopolycarboxylic acid of the following formula (I) and the bath having fixing ability contains at least one organic phosphonic acid: <CHEM> wherein n represents 3, 4 or 5, and is preferably 3. Especially, the bleaching agent in the bath having bleaching ability comprises at least one iron(III) complex of a compound selected from the following group (A) and a (1,3-diaminopropanetetraacetato)iron(III) complex in a molar proportion of the former to the latter of being 3 or less, and ammonium ion accounts for 90 mol% or more of the sum of the alkali metal ions and ammonium ion in the bath having fixing ability; Group (A): A-1: Ethylenediaminetetraacetic Acid A-2: Diethylenetriaminepentaacetic Acid A-3: 1,2-Cyclohexanediaminetetraacetic Acid A-4: 1,2-Propylenediaminetetraacetic Acid. According to the method, rapid desilvering is effected, the stability of the fixing agent is improved, bleaching fog is inhibited, the fixing speed is elevated, and the storage stability of the images formed in the material processed is improved.
